Email not working when overseas on WiFi, works on cellular

Thanks for reaching out. I completely understand the importance of accessing your account, and I’d be reaching out too if I were in your position.

What you're likely experiencing is a security measure designed to prevent access from overseas IP addresses. These protections are in place to help safeguard your account from unauthorized activity. As you mentioned, using a VPN is typically the best workaround in these situations, and it’s great that you’ve already taken that step.
